DUMPING APPARATUS.

SPECIFICATION forming part of Letters Patent No. 406,404, dated Jiily 2, 1889.

Application filed May 25, 1888. Serial N0.275,4ll. (No model.)

To all whom it may concern.-

Be it known that I, GEORGE W. PATNOE, a citizen of the United States, and a resident of Crawford, in the county of Cook and State of Illinois, have invented new and useful Improvements in Apparatus for Dumping Cars, of which the following is a specification, reference being bad to the accompanying drawings, two sheets illustrating the invention, in

to Which-'- Figure 1, Sheet 1, is a perspective representation of my invention in apparatus for dumping cars, with the car and a section of track in position as when the car is inclined I 5 to dump its load of stone. Fig, 2, Sheet 2, is a longitudinal vertical sect-ion of the dumping and stationary portions of the track and an elevation of the car on the stationary track and the dumping-track, the line of section being indicated by dotted lines as, Fig. 1. Fig. 3 is an enlarged elevation of the clutch on the car and a cross-section of the flanged track by which the car is held to the dumping portion of the track when the car is being dumped. Fig. 4 is a cross-section of the car and dumping-track on dotted line 2, Fig. 1, looking in the direction indicated by dart y. Fig. 5 is an enlarged elevation of the spring trip-lever and pin which hold the dumping 0 track in line with the main track till the car is to be inclined to dump its load.

This invention relates more especially to improvements in dumping apparatus for handling stone; and the gist of the invention 5 in brief consists in a suitable car and a track, a portion of which is journaled to incline on such an angle as is required to dump the stone from the car. The dumping-track is provided with a spring trip-lever and pin. by which the 40 journaled track is held in line till the car comes in contact with said lever, at which time the car and the journaled track will be properly inclined for the load of stone to slide off. The under side of the car is provided with a clutch, which is free from contact with the stationary track, but which engages an elevated flanged central rail on the dumping portion of the track after the car has partly passed onto the latter, and is thereby held firmly in position on the track when inclined for the stone to be dumped. The track, being weighted on the opposite side from where the stone is dumped, automatically adjusts itself in line with the stationary or main track so soon as the stone is removed. In order to stop the car on the dumping-track, a springbuffer is secured to the said central flanged rail in the position for stopping the car at the time the car-axle or other part of the car operates the trip-lever to release the pin, as the whole is hereinafter fullydescribed and shown.

A A represent a portion of the stationary or main track, on which a car 0 is caused to move by suit-able means in the direction of dart z with a load of stone thereon, the track having anydesired inclination.

The track for the journaled part is shown at B, and it is affixed to a strong bed-support D, which is made to have greater Weight at its back portion that it may automatically return in line with the main track A A after stone has been dumped from the car.

Attached to each end of the bed-support D is a strong bracket E, to which is secured by strong bolts or other suitable means a central rail F, whose ends are made cylindrical, and to have bearings in boxes G G, which are rigidly secured to the cross-timbers of the main track, or timbers especially employed for that purpose, so that both tracks shall be in line when the car 0 is not inclined to dump the stone thereon. The rail F is flanged outwardly at its upper portion to engage a strong clutch H, secured to the under side of the car, as more clearly shown at Fig. 3, where a broken port-ion of the bottom of the car C is also shown.

The flanges on the rail are shown at K K, and the engaging ends of the clutch at L L.

The spring-buffer is shown at I J. I is the headed push-pin, and J is the case in which 0 the pin has a reciprocating movement, and which contains the coil-spring of ordinary well-known construction, as separately considered. The case J is rigidly secured to the rail F, and in practice that portion of the end 5 Mof the car comes in contact with the. pin I. The trip-lever is shown at a, and enlarged and removed as at Fig. 5. It is pivoted to the bed D at b and to connecting-rod c at m, and the rod 0 is pivoted to a pin (1, which engages a socket-p1atc f, afiixed at n to one supporting-timber N. In the outer end of the socketplate f is placed a headed rod 0', on which is a helical spring, and on the outer end of the rod is a nut s. The lever a at p is connected with a helical spring in a case g. The spring in the socket-plate f exerts its force in an opposite direction to the spring in case g,whereby the lever a is held in an upright position unless tripped by the car, and, so soon as the car releases the lever a, will again return to its normal position-that is, re-enter the socket-plate f and lock the dumping-track in alignment with the main track. Vhere it is desirable to have two or more dumping-sections with a main track for dumping stone in. different places in boxes, bins, or onto cars, any one dumping-section can be secured to such main track (so that the car may be driven overit) by means of a pin 0;, Fig. 2, put through a part of the said main track or its support and into the bed D of the dumping part. In such a case only the buffer I J would have to be removed, as the lever would incline in either direction and permit the ear to pass back and forth.

I claim as new and desire to secure by Letters Patent A dumping apparatus comprising the bed D, )ivotally supported in alignment with the main track A, and provided with the central rail F, having flanges K, a buffer I J, attached to said rail, a lever a, pivoted to said bed and having a connecting-rod c and a, pin cl, a socketed plate f, connected with a fixed support to receive said pin, and a spring joined to the lever and the bed, all adapted for operation in connection with a truck carrying the clutch II Ii, substantially as described.
